In this day with horse sales going down the toilet and hay prices going up like crazy, if you are interested in a horse, especially a nice one, you have to act fast. If you wait, you lose the chance of getting the horse because most sellers are going to not hold a horse unless a deposit is made.
I have sold horses, had someone come look at them, say" oh I really like him, will be back tomorrow or the next day to pick him up" and never see or hear from them again. Then of course, you have told others he is sold, and lose that sale also.
Next time if you find a horse you are interested in, give a deposit and have a contract already written up stating deposit will go towards purchase price if horse vet checks sound, etc. Then you need to do it quick, within a day or so at the most. Give a time frame, make an agreement and follow through, if you don't then you lose deposit.. If the seller won't sign a paper about passing vet inspection or some other excuse, then probably not a good horse anyway.
I am funny about buying things. I live in the middle of nowhere and usually have to drive two or three hours minimum one way to see horses, trailers, etc.But, I go planning to buy and do so right then. I don't go see something, then leave and expect to go back in two or three days and have it still waiting for me. I have hauled a trailer 8 hours one way to go look at the perfect horse, then got there and found a horse that was lame, etc. Left with an empty trailer. I have driven hours to look at horse trailers and found rusty buckets of metal. But, usually I am sure of what I am looking at before I drive.
If you like something, don't wait, cause if its nice and what you want, somebody else is probably waiting in the background for an opportunity to buy it.
